The head 24 of hecyl'nder ,is provided akie aes g shaft23iiivhicl1 'nected with a portion, of;the pipe '26 as val ve housing 27 with which shown more clearly in Fig. 3.

A valve seat 30 is arrangedwithin the a valve 31 cooperates.

An elastic member 32 such as a coil spring orthe like, is provided, one end of which has connection with the valve 31 and the other end rests within a cap 33. ,This cap 33 is removably secured to the valve housing 27 so' as to close anopening therein, as shown, and serves as a means whereby access may be had to the valve 31. The normal tendency of this elastic member 32 is to move the valve 31against its seat 30 so as to shut off the flow of liquid through the valve housing.

A valve stem 34 is provided on the valve I 31 and this stem passes through a suitable bushing or packing box 35 and preferably projects above or beyond the valve housing 27. t

A casing 36 is provided for protecting the end of the stem 34 .and thiscasing may be of any desired size and construction, the

lower end 37 of which is provided with internal screw threads adapted to coiiperate with screw threads on the portion38 of the valve housing.

The casing 36 is provided with an opening 39 in the top thereof and the casing 1s preferably of some length. Pro ecting through the opening 39 in the top'of the casing is a bushing 40 having a shoulder 41 engaging the inner face of the top of the casin g and a nut 42 surrounds the bushing 40 and cooperates with peripheral screw threads thereon to serve as a'means whereby the bushing 40 may be secured against displacement with respect tothe casing 36. This 4 bushing 40 is provided with an opening having communication with the interior of the casing 36 and is provided with internal screw threads 43 with which screw threads on one extremity of a tubular member 44 cooperate to secure or connect the tubularmember 44 with the casing 38. This tubular member 44 may be of any desired diameter and length butis preferably of a length so that itsupper end will terminate adjacent the guide 21. The upper extremity of the tubularQmember is also provided with peripheral screw threads, and the end is adapted to projectinto a threaded boss 45 for the purpose of housing thecontrolling mechanism, to be presently described.

Projecting through one of the walls of thehousing 46 and 'ournaled'in asuitable bearing 47 is a sha t 48, one extremity of which projects for housing and is provided with a worm gear 49 on the extremitythereof. The bearing 47 is secured against displacement in any desired or suitable manner, preferablyby means of a fasteningdevice 50. The extremity of the hearing which is located outside ofthe housing 46 is provided with a some distance intothe flange 51 having a recess 52 in the outer face thereof, and the shaft 48 is of such a length that the end 53 thereof will project through the recess 52 and beyond the outer face of the flange 51.

Arranged within the recess 52 is a ratchet member 54 having faces 55 which coiiperate with the wall of the recess 52. Rollers 56 are arrangedwithin the recess 52 adjacent the faces 55 of the ratchet element 54 and a shoulder 57 is also provided in the ratchet element 54 for each of the faces '55.

An elastic member 58 is disposed between each of the faces 57 and the respective rollcrs 56and tend normally to force the rollers 56 against the wall of the recess 52.

'When the shaft 48 is rotating in the direction indicated bg the arrow in Fig. 6, the springs 58 will e compressed to a certain extent and themen'per 54 will force the rollers 56 around the recess 52. If, however, ,the shaft 48 is rotated in a direction opposite to the direction indicated by the arrow in Fig. 6, the faces 55 will force the rollers 56 into engagement with the wall of the recess 52 and thereby lock the shaft 48 against rotation. The ratchet of element 54- is secured to the shaft 48 for rotation therewith in any suitable manner, preferably by means of the fastening key 58. A similar ratchet element 59 (see Fig. 5) is also keyed to the shaft 48 by means of the'fastening key 58 but this ratchet element 59 is located outside of the recess 52, and'is provided with faces 60 corresponding to the faces 55 of the element 54 and shoulders 61 corresponding with the shoulders 57 of the element '54. These ratchet elements are preferably of substantially the same diameter'and arranged to inclose the ratchet element 59 is a sleeve-62, the peripheral flange 63 of which extends over the periphery of the element 59,'as shown more clearly in Figs. 5 and 9.

Friction rolls 64 similar to the rolls 56 are provided in each of the spaces formed by the shoulders 61 and faces 60 of the element 59. and elastic members.65 are also provided between the shoulders 61 and the will tend to compress the wall of the recess 52 to 66 and one end of this shaft 66 abuts the end 53 of the shaft 48. Bracket 21 is provided for the casing 46 and the shaft 66 is held in position in any desired or suitable manner,'

preferably by means of fastening 1 devices 68, such as cap screws, which pass through flange 51 and the member 67 and screw into the bracket'21. From the mechanism thus far described, it will be apparent that when the shaft 66 is rotated in one direction, or a direction tocause the'peripheral flange 63 to rotate in the'direction indicated by the arrow in Fig. 5, the rolls 64 will be forced against the faces 60 of the element will be locked for rotation by the peri aheral flange63 and as this element 59 is ast to the shaft 48, it will be apparent that the shaft will also be rotated. During this rotation of the peripheral flange 63, and consequently of the shaft 48, the element 54 will be rotated in the direction indicated by the arrow in Fig. 6, and the shoulders 57 the springs 58 to force the rolls 56 around the wall of the re cess 52. \Vhen the direction of rotation of the shaft 66 is reversed, the peripheral flange 63 will tend to force the rolls 64 in a direction toward the shoulders 61 to com? press the. elastic permit the peripheral flange 63 to rotate independently with 'respect to the shaft 48 and also the element 59. During this reverse rotat on of the pehinheral flange 63, any tendency of the shaft 48 to rotate in the opposite direction will be overcome by, the element 54 as this element will also tend to rotate in the oppos te direction to cause the faces 55 thereof to force the rolls 56 against bind or lock the element 54 aga nst rotation.

The shaft 66 may be rotated n any desired or suitable manne p eferably by means of a crank or handle 69 and inorde to m art the rotation of the shaft 66 to the pin on 29. wh ch ra ses and lowers the rack 9 and conse uentl the p ston 18, a gea 70 is pro ided. on-the shaft 66 which meshes with 'a gear 71 s cured to the shaft 23. as c ea ly shown in Fig. 1.

' Arranged within the housing 46 and proiecting efe ably f 'om the ear wall thereof is stud o" axle 72 and this stud or axle passes drum 74. for some d stance d um 7i. and the d 'um is p o ided with an The hub 7 3 preferably proiects open side preferably disposed toward the rear wall of the housing 46.

Arranged withinthe housing and through 55 of. the element 54.. The sleeve 62 is secured for rotation'to. a shaft a fast'enin 59 so that the latter the gear seemed as at 83 to secured as at 84 to the members 65 and this will.

erally beyond the rear face of the gear eccenir callv' th ough a hub 73 of a bevond each s de of the which the stud or axle 72 passes is an element 76 preferably in. the form of a bracket having a flanged-portion 77 and a'hub 78 against which one extremity of the hub. 73

of the drum 74 rests. The 9 ring drum is held against accidental di'sp acement with respect to thestud or axle 72 in any desired or suitable. manner preferably by means of device 8 which passesinto the free end 0 the. axle and through a washer,

the edges. of thank.

' Mounted to rotate loosely of the spring tweenthe drum and the element 76 is a worm gear wheel 80 which is provided with a hub 81. Thefhub 8 1 is preferably of such! a length that one extremity will rest against the projection 78- of the element 76 and the other end will project into the drum 74 through the open side thereof. The drum 74 ispreferably of .a diameter somewhat larger than the diameter of the hub 81 of 80 and an elastic erably in the form of a coil spring 15 are ranged within the drum and is coiled about member 82, prefupon the hub 73 drum, and preferably be- I the adjacent portion of the hub 81 of. the" 80. One extremity of the-spring IS the hub 81 of .the gear 80 and the other extremity of the spring is drum.

Arranged upon the element 76 and pro jecting toward the gear 80 is a projection or extension 85 which'is preferably provided with a recessa-dapted to receive an elastic member 86 which latter 15 preferably in the I This sprin is of form of a coil spring.

wi l norsuch a length that one extremity mally project beyond the recess in the proextension 85 to be engaged by a jection or 87 carried by and extendmg lat prci ecti on The spring 82 in the drum 74 is arranged in such a manner that it will tend normally tomove the projection on the gear 80 into engagement with the elastic member 86 carried by the projection 85, which a ts as an elastic bumper upon the return of the gear.

Secured to the-other extremity of the hub 73 of the drum 74 is an operat ng handle 88. by means of which the hrb 73 of the drum 74 may be rotated about the stud o axle The gear 80' s arranged n proximity to the wo m gear 49 on the shaft 43 and is of such a diameter that 88 is in the position shown in ig. 7.. the

I gear 80 will be moved. out of mesh with the gear 49. If. howe er.

the onerating handle 9-8 is mo ed from-the position shown in Fig.

7. toward the left. the hub 73 of the drum 74 will be rotated eccentrically about the stud or axle 72, which will bodily shift the ear 80 so that the periphe al teeth thereof will be mo ed lnto mesh with the worm gear 49 In this pos tion, it will be apparent when the operat ng handle l The in a direction to create a tension'on the coil spring 82 and to also move theprojection 87 away from the projection "85 on the element 76. The drum 74 thus described is connected with the valve 31 and serves as a 'means for opening the valve to permit the liquid to flow through the valve housing" 27 when the handle 88 is moved from the position shown in Fig. 7 toward the left and for this purpose there-is provided a bar or rod 89 which passes through the tubular member 44 with one of its extremities threaded as at 90 and which extremity projects into the casing 36. An adjustable sleeve 91 is threaded on this extremityof the rod 89 and is preferably provided with a recess 92 into which'the free extremity of the is moved to the left from the valve stem 34 of the valve 31 projects.

A lock nut 93. may be provided on the bar or rod 89 for locking the sleeve 91 against accidental adjustment. of this bar or rod 89projects through the boss 45 on the housing 46 and into the housing through an opening in the bottom thereof, This extremity of the' 'ba1' or rod termi- The upper extremity nates adjacent the face of the drum 74 and is bifurcated as at 94. Into this bifurcated portion a lug or projection 95 on the drum 74' projects and serves as a means whereby the extremity of the bar or rod 89 is connected to the drum. This projection 95 is preferably provided with a head to prevent accidental and lateral disengagement of the bar or rod with respect'to the drum. Thus it will be apparent that when the handle 88 position shown in. Fig. 7 and the drum 74 is rotated, the projection 95 thereon will force the bar or rod .89 downwardly to unseat the valve 31 against the tension of the elastic member 32 and the valve 31 will remain open so long as the parts arein the position just described. It will also be apparent that if the handle 88 should be released, the elastic member 82 would tend to move the handle 'back intothe position shown in Fig. 7 from the adjusted position and thereby move the gear 80 out of mesh with the gear 49 and the projection 87 of the gear into engagement with the spring 86. In order to prevent this operation, and to maintain the gears 80 and 49 in mesh for a predetermined period, without necessitating the operator ho ding the handle 88 and the parts in this adjusted position, suitable mechanism for locking the parts in the ad usted posit on to maintain the gears 80 and 49 in mesh and the valve 31 open, and for also automatically releasing these parts to permit the valve 31 to close at a predetermined period, will now be described.

Projecting radially from the drum 74 is an arm or extension 96 which 'is provided with a shoulder 97 and this arm 96 is so positioned that when the handle 88 is ad justed to the left from the position shown in Fig. 7 to open the valve 31, the shoulder 97 will be engaged by a spring controlled dog 98 which is pivotally mounted prefer ably upon the bracket or element 76.

Carried by the face of the gear 80. is an extension 99 mounted in which is an adj ustable element 100 preferably in the form of a screw or bolt. The dog 98 is provided with an arm 101 which normally projects in the path of the movement of the element 100.

As has already been described, when the parts are adjusted to move the gear 80 in mesh with the gear 49, the valve 31 will be held open and will be locked open by the engagement of the shoulder 97 with the dog 98. It has also been stated that when the shaft 48 rotates, the gear 49 will operate to move the gear 80 in a direction to create a tension on the spiral 82. This direction of rotation of the gear 80 is indicated by the arrow in Fig. 7. After the parts have been thus adjusted and locked, they will remain in this position until the element engages the arm 101 on the dog 98. A further movement of the gear 80 in the same direction will then cause the element 100 to rock the dog 98 so as to move the latter out of engagement with the shoulder 97 on the arm 96 "against the tension of the elastic member 102 and the drum 74 will be then released. When thus released, the tension which has been created upon the elastic members 82 and 32 will move the drum 74 in a clockwise direction. As this drum is mounted eccentrically upon the stub or axle 72 it will be manifest that this reverse rotation of the drum will cause the gear 80 to be bodily moved out of mesh with the gear 49. When out of mesh, the spring 82 will operate on the gear 80 to rotate it in a direction to cause the projection 87 to move into engagement with the elastic member 86 carried by the projection '85.

,By adjusting the sleeve 91 on the end of the bar or rod 89 it will be apparent that the time of opening of the valve 31 may be varied and by providing the bifurcated ex- The housing 46 is provided with a closure 104 by means of which the controlling:

mechanismthus described may be completely incased and locking mechanism ill) designated generally by the reference numeral 105" is provided for locking the closure closed and this lockin mechanism may be of any type, preferably of a type wherein a key is employed to actuate the same.

It is thought that the operation of this improved ap aratus will be clearly understood from he description given and with this improved construction it will be manifest that the controlling mechanism may be set in the manner described by any ant iorized )erson and when thus set the casing 46 may be locked. The pump may be thus set into operation by the operation of the handle (39 and will continue to actuate by the operation of this handle to discharge liquid through the pipe 20, which latter may be arranged to convey it to any desired point of use. until a predetermined quantity has been discharged. This predetermined quantity may be controlled by the adjustment of the element 100 to vary its time of engagement with the arm 101 of the dog 98. When this element does engage this arm 101, it

will be manifest that the dog will be trip ed, the parts released, and the valve 31 \\ll be seated by the elastic member 82 and this elastic member 82 will also operate to rotate the sprin drum 7-!- altout the stud or axle 72 in a irection to move the gear out of mesh with the gear 45).

In order that the pum may be employed for other purposes, see 1, for instance, as discharging a quantity of liquid at the pump, a discharge nozzle 105 of any desired or suitable type may be'employed (see particularly Figs. 1, 2 and 3). 'his nozzle is connected with an extension 106 leading from the discharge outlet 25 of the pump cylinder and this nozzle 105 has commumcation with the pump cylinder or discharge thereof preferably on the side of the valve housing 27 adjacent the inlet of said housing.

Thus it will be manifest that even though the valve 81 is seated to prevent the liquid from being discharged through the pipe 26, liquid may be discharged from the pump through the extension 106 and valve 105 when the latter is oper.
